TWO years after the first New York City Ballet workout video leapt off the shelves, there’s fi nally an encore.

Out today is “New York City Ballet Workout 2,” and, like its predecessor, it requires neither toe shoes nor a tutu.

It does, however, require good balance – especially when you’ve raised both arms above your head and are trying to lift one leg past your ear, in what’s grandly called a “grand battement.”

That term and others are duly demonstrated and explained – there’s even a glossary at the end, though by then you won’t need one – but it’s your body that may require translation. The less limber you are, the tougher you’re going to find this workout.

Like the earlier tape, this one leads you through warm-ups, stretches and floor work, most but not all drawn from ballet: Yoga devotees will recognize the “plank” (where you balance yourself on your elbows and toes), one of the exercises that works the abdominals.

Not for the weak of knee are the demi pliés (the bending and pressing back of the knees until they extend over the toes). And the choreographed moves at the end of the tape – in which the dancers leap around in George Balanchine’s “Tarantella” – may leave you winded and wishing you were lying down, preferably with a nice glass of wine.

All told, “Workout 2” is tougher going than the first, even with the soothing strains of Bach, Beethoven and Mozart behind you. (The DVD also offers a “contemporary” soundtrack featuring the likes of Cousteau and Baaba Maal.)

And while we only heard ballet master Peter Martins’ dulcet Danish tones as he directed us in the first workout, on this tape we get to (briefly) see him in glasses, looking a little sad and vaguely disapproving, as if he’s eyeing you in your sweats and knows you’re no match at all for his four gorgeous dancers.
